TDK has shrunk its 500V gate drive transformers to 11 x 13mm and 11mm high, smaller than its existing E10EM series. The new parts, called the EP9 series and aimed at both IGBTs and mosfets, are built on a MnZn ferrite core with surface-mount L-pin construction. Creepage and clearance is 5mm, peak withstanding is 2.5kVac 50Hz, and coupling capacitance is ...

Infineon is launching a RISC-V starter kit for a family of automotive microcontrollers to be released “within the coming years”, the company said. “In software-defined vehicles, RISC-V is key to standardisation and ecosystem compatibility,” claimed Infineon’s automotive president Peter Schiefer. The kit will be provided by Synopsys, and is intended to spur the development of virtual MCU prototype for software development ...

EV and fuel cell vehicle sales grew 25% in 2024 to 16.9 million units, says TrendForce, with China expanding its market share to 67%. In 2025, EV sales are projected to grow by 18%. Tesla retained its top position in BEV (battery EV) sales in 2024, with BYD closely following in second place. SAIC-GM-Wuling saw an impressive 44% YoY growth, ...

TDK has created inductors for automotive power-over-coax applications up to 1.6A. The three parts are an expansion of the 4.5 x 3.2 x 3.2mm ADL4532VK series, and are rated for use across -55 to +155°C. Power-over-coax requires data to be separated from power, and that filtering is what these inductors are intended for. The “series delivers high impedance across a ...

TDK has announced two series of Pb-free bead thermistors. “Both series are Pb-free and can measure temperatures between -40 °C and +155 °C,” according to the company. “At room temperature, their maximum power dissipation is 60mW. Both series are available with different rated resistances between 1kΩ and 100kΩ and different R/T characteristics [see table]. After 10,000h at +70°C, the deviation ...

Littelfuse is aiming at electric vehicle battery management systems with its latest transient voltage suppressor diodes. Specifically, the unidirectional diodes in the TPSMB-L series are for protecting analogue front-ends and IC in 14 to 20 cell  sub-assemblies. There are three parts, all rated for 600W 10/1,000μs pulses (0.01% duty cycle) and come in ~3.6 x 5.3mm DO-214AA (SMB) packaging: Reverse ...

Mouser is offering PCIe 5.0 cable-to-board connectors from Molex that provide 12 power pins and four signal pins. “These connectors comply with the latest PCIe CEM 5.0/6.0 specifications and support devices requiring AIC [ampere interrupting capacities] of up to 675W”, according to the distributor. The 600V (dc or peak ac) 9.5A power pins have 5mΩ resistance and suit 16 AWG ...

Omron has designed a relay that can interrupt 200A at 500V, aiming to displace contactors from dc electric vehicle chargers, batteries and solar inverters. “A proprietary gas-less design cools arcs without the need for any special parts or materials in the manufacturing process, while eliminating the possibility of gas leakage,” according to the company. Gas-less? “G9EA, G9EC, and G9EH relays ...

Japan is investing $660 million in ASSB (All-Solid-State-Battery) R&D with the target of commercialising the technology by around 2030. Japan possesses the most ASSB-related patents in the world and has been steadily establishing a supply chain over recent years with the target of achieving mass production, reports TrendForce. Japan’s Ministry of Economy, Trade and Industry (METI) announced the “Battery Supply ...

AL8866Q is an AEC-Q100 (Grade 1) qualified dc-dc converter controller aimed at automotive front lights such has headlamps. In needs an external n-channel power mosfet, and can implement buck, boost, buck-boost or SEPIC (single-ended primary-inductance converter, pictured) topologies. Operation is from 4.7 to 85V, covering 12V, 24V and 48V battery power rails. Analogue and PWM dimming are possible via a ...
